Look it is an adult sippy cup!!! This is CUPPOW - our solution for easier drinking from a canning jar. The canning jar already makes an awesome platform for a travel mug: it's easy to clean, made of heat-resistant glass, cheap, durable, and when sealed it doesn't leak. The only problem is that with their large openings, canning jars are not great for spill-free sipping while on the move. So we adapted it - made a new lid that lets us drink like a boss from virtually any wide-mouth canning jar.

Cuppow! Turn a canning jar into a travel mug. I like the idea of this, even though I'm not one of those people who likes to use jars for everything. Also, I think it would need some sort of a sleeve (possible knitted or felted) for hot drinks. Anyway, way to represent, Somerville, MA!

This is genius! Who knew? Parmesan cheese containter lids will fit on mason jars! How about keeping baking soda by the sink for a mildly abrasive cleanser. Or flour near where you kneed your bread - just sprinkle on the counter.
